摘要： 为提高串联故障电弧检测的可靠性，依据标准搭建串联故障电弧检测试验平台，设计数据实时采集装置采集了白炽灯、日光灯、空气压缩机、吹风机4种线性或者非线性负载在正常和故障情况下的电流数据共9 600组。提出利用一维卷积神经网络（1D-CNN）检测线路中电流信号对其分类，判断是否发生故障电弧。经测试该模型对各类负载的平均检测准确率达到100%，损失值在0.000 7以下。将模型导入嵌入式系统，准确度达到96.25%,证明设计的卷积神经网络架构可成功检测出串联故障电弧，降低火灾发生风险。

Abstract: In order to improve the reliability of series fault-arc detection, an experimental platform is built according to the standard, and a real-time data acquisition device is made to collect both faulty and non-faulty current data generated by 4 types of linear or non-linear loads, including incandescent lamps, fluorescent lamps, air compressors and blowers. A one-dimensional convolutional neural network (1D-CNN) is proposed to inspect current signals in the circuit and determine whether fault arcs occur. Testing results show that the average detection accuracy of the model for all kinds of loads reaches 100%, and the loss is below 0.0007. We also transplant the model into an embedded system, and the accuracy reaches 96.25%. It is proven that the designed convolutional neural network structure can successfully detect series fault arcs and reduce the risk of fire.
